There are only four team and on paper the only one who has the best chance and performance is Leverkusen so I not sure Atalanta and Roma will be able to apply pressure that really makes things difficult for Leverkusen.
For Roma, it is clear that they will be Leverkusen opponents in this semifinal, but even though Roma performed quite well in Serie A, that will never guarantee that they can play well in the Europa League.
In this semifinal, it is clear that Leverkusen is the favorite and Leverkusen is the team that can make this European League theirs, Roma, Atalanta and Marseille are just teams with quality that is still below Leverkusen.
Look, Leverkusen has received lot of praise and is also acknowledged by everyone that they are strong team, even this season they have title award for their achievements.
I sure Xabi won't let it all go away quickly, he will definitely be able to bring Leverkusen to much better start this season.
We have just 5 more matches left in this season while we are having now all four-best teams left in this competition which are going to give their best in remaining games which will allow them to have won the title even things are clearly favouring Bayer Leverkusen for having win but still we can't predict about few things with Atlanta and Roma both are doing good, and we are also having now Marseille which is not strong enough as we have them in the Past, but they can also give surprise which will be allowed them to have final of this event.
Roma and Bayer Leverkusen are already having matches in last season which was won by Roma, but now we have good changes in teams with improvement of quality is also matter so can Bayer Leverkusen keep their unbeaten record, or we are going to have Roma is jumping for another final which could be also interesting.
Overall, we have 5 matches remaining in the Europa League, 4 semifinal matches and 1 final match which will determine which team is truly strong and worthy of winning the Europa League title this season.
In about week the first leg match will start and this will be the initial match for the team with its superiority to be able to get more favorable aggregate for the settlement of the second leg later.
Marseille vs Atalanta, the first leg match will give Marseille the advantage on paper because they are playing at home, this is good opportunity for them because in the second leg Atalanta will have the home advantage and Atalanta is not weak team.
Marseille must win big in the first leg if they want to have good chance of qualifying for the final, the second leg will be big pressure for Marseille if they don't win big in the first leg.
Roma vs Leverkusen, in this first leg Roma has the advantage of playing at home but Leverkusen in the away match also performed quite well and I think this match will be unlikely for Leverkusen to lose.
In the Roma vs Leverkusen match, I don't think we need to discuss it much because it is clear that Leverkusen will definitely be the team that will qualify for the final, moreover there is second leg match which will provide home match for Leverkusen.
